Giro Prolight Road Helmet

In 1985, the original Giro Prolight set the standard for modern lightweight cycling helmets. Now, 25 years later, the new Prolight redefines what an ultra lightweight helmet can be. After an exhaustive, ground-up design and engineering process, Giro has created a helmet that tips the scales at only 200g -- simply the lightest CPSC race helmet in the world.

In-Mold construction provides strength, integrity and is so lightweight, you'll have to remind yourself that you've got a helmet on at all
